Application filed December 8, 1926. Serial No. 153,430.

This invention relates to chinery and has special barrow,

More particularly agricultural mareference to a the invention relates to improvements in my prior Patent Number 1,605,183,

One important object to provide an improved issued November 1926.

the invention is form of hitch for harrows of this description.

v A second important object of the invention is to provide an improved means for supporting the. movable handles in a harrow of this character.

A third important object is to provide an improved bars tooth supports and that the teeth will of the invention arrangement of teeth so constructed act upon the ground. on

each side of the harrow, at evenly spaced intervals in a lateral direction.

lV'ith the above and other ob3ects in view as will be hereinafter apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying draw cally claimed.

In the accompanying drawings like char like parts in the acters of reference indicate several views, and:

ings and specifi- Figure 1 is a perspective view of a harrow constructed in accordance provements.

Figure 2 is a plan view such a harrow in their tened out and showing position when the spacing of the with these imof the frames of flatbars and arrangements of the teeth.

Figure 3 is a perspective and its holder from the front of the face bar which carries the same.

view of a tooth Figure 4 is a similar perspective view at right angles to Figure 3.

Figure 5 is a perspective view of one form of scraper blade used herewith.

Figure 6 is a perspective view of a guard used herewith to keep the harrow teeth from going too deep next to the plants.

In the present embodiment of the inven tion the main part of each of a bar of metal rectangular and bent to form an inner frame member '10 the members the complete harrow two frames forming in cross section longitudinal 10 of the being closer together at the front than at the rear and held means of interengaging eye nuts on each side of the in adjusted position by bolts 11 having frame so that by frame consistsv I there. lbloreover, the interlocking eye bolts permit tilting of the frames with respect to each other so that the harrow may be used on fiat ground, on ridges formed by throw-t ing up the dirt and in the furrows between such ridges. At each end of the respective members 10 the bar is bent to extendlaterally as at 13 and at the forward end the bar is bent at about forty-five degrees to the rear as at let, this forming a termination of this end of the bar. Fromthe outer end of therearportion 13 the bar is carried forwardly with suitable bends and inclinations as shown at 15 and terminates in anangular portion 16 lying on the outside of the part 14 and secured thereto by bolts or rivets 17. This forms the main part of each frame member. On the outside of the part 1:") there is provided an outer frame member 18 having an inclined forward end 19 which lies against the partlG and is secured thcrcto by bolts or rivets 20. At the rear end of this portion 18 the bar, which is of the same cross section asthe bar 10, is bent-inwardly as at 21 and lies against the outer face of the outer end of the rear part 13, being secured thereto by bolts or rivets 22. Connecting the two parts 13 is an intermediate spective end ofra diagonal bar 26, the reone bar being secured to the part 10 and of the other bar being secured to the part 15. Clips 27, preferably of the type used to hold wire rope and the like, are utilized to secure barrow teeth 28 in position on the various longitudinal end diagonal bars and on and these clips and the teeth 28 are so disposed that the lateral spacing of the teeth is uniform throughout the extent of each of the two frames forming the complete hau row as will be clearly seen by reference to Figure 2 wherein the dotted lines typically indicate the paths of these teeth with the barrow moving forwardly over the ground in fiat position. Obviously, this spacing is in no ways affected by the angular inclination of the frames so far as regards its evenness upon the ground being worked. Scrap er blades 29 may be secured to the portions and 15 and short scraper blades30 may be secured to the portions 18, the securing niaining end of the portions 13 and 21 means being preferably bolts and nuts so that these blades can be removed at will.

Each frame is provided with a handle or stilt 31 carrying at its forward end a metallic extension 32 pivoted to the respective forward frame portion 13 as by a pivot bolt 33. The rear of each of these stilts or handles is provided with a hand grip Sit.

On each frame at the rear thereof there is pivoted a. bar 35 which extends up along the inner side of the respective handle 31 and is secured adjust-ably thereto by means of a bolt 36 passing through one of a series of openings 37 formed in the upper end of the bar 35. The brace bar 38 is also pivoted to the rear of each frame and this brace bar is connected to the respective bar 35 by a bolt 39 passing through a selected opening It in the brace bar 38 and through a selected opening 41 in the bar 35. By this means the positions of the hand grips 3% may be adjusted to suit the user of the barrow and to the inclination at which the two halves are intended to work.

In order to draw the harrow over the ground links 42 have their rear ends connected to the rear members 13 and the forard ends of these links carry chains in which are united to a single ring it to which the donbletree or other draft of plants may be connected. In order to adjust the inclination of the links 42 and chains 43 so that the ring it will be of properheight there are also provided short chains each of which has one end connected to the respective bolt 38 and is provided at its other end with a hook 4.6 which may be hooked into any one of the links of the respective chain 43. Naturally,by engaging links close to the ring ehl the ring will be pulled down while by engaging links close to the members l2 the ring 44: will be allowed to rise.

There has thus been provided a simple and etfieient device of the kind described and for the purpose specified.

It is obvious that minor changes may be made in the form and construction of the invention without departing from the material spirit thereof. It is not, therefore, desired to confine the invention to the exact form herein shown and described, but it is desired to include all such as properly come within the scope claimed.

Furthermore, it will be noted that the side members 18 are ren'iovahle so that the barrow may be used between ions too narrow for full width barrows.

Having thus described the invention, what is claimed as new, is: i

1. In a barrow, a pair of frames hinged together along the longitudinal center line of the harrow, means to adjust the front and rear portions of said frames independently toward and from each other, a pair of bandles each pivoted to the forward portion of a respective frame, a pair of links each pivoted to the rear portion of a respective frame, means for connecting the handles adjustahly to the links, brace links pivoted to the rear portions of said frames. and means to adjudablv connect the brace links and the first mentioned links.

In combination. a pair of barrow frames, means for connecting said harrinr frames hingedly and adjustably, each of said barrow frames including front and rear transverse members, links each having one end pivotally connected to the rear transverse member of a respective frame. chainshaving their rear ends connected to the front ends of said links, a ring to which the trout ends of said chains are connected, other chains each having an end connected to the front transverse member of a respective frame, and hooks carried by the free ends of the last mentioned chains and engageable with selected links of the first mentioned chains.

In testimony whereof I attix my signature. JAMES B.
